August 7, 2015: Further to AAVSO Alert Notice 525, we are entering the critical period of observations for KIC 02856960. Time series observations are urgently requested for this eclipsing binary beginning immediately (2015 August 07, JD 2457242) and continuing for the next five days, through the end of 2015 August 12.

August 4, 2015: Dr. Gregory Sivakoff (U. of Alberta) has requested optical monitoring of the galactic microquasar V4641 Sgr beginning immediately, and continuing for the next 120 days, or until it is no longer observable from your location.

December 6, 2013: Observer Carlo Gualdoni reports via the cvnet-outburst mailing list that the WZ Sge-type dwarf nova AL Comae is in outburst, with a magnitude of V=12.74 on 2013 December 6.185 (JD 2456633.1185). Gary Poyner notes on the BAAVSS mailing list that this is the first observed outburst of AL Com since October 2007. Both visual observations and CCD time series are encouraged.

February 14, 2011: Further to AAVSO Alert Notice 428 (2010 Nov 30), the dwarf nova FS Aurigae appears to be in outburst. The current outburst was detected simultaneously by P. Lake (Wonga Park, Victoria, Australia) at m(vis)=14.5 on 2011 Feb 14.0969 (JD 2455606.5969), and confirmed shortly after by G. Lubcke (Middleton, WI, USA) at around V=14.4 in time-series observations made simultaneously to the observation of Lake. Follow-up photometry of this star is encouraged.
